Life is beautiful, and not because x, y, or z happened. When you say “I’m happy because this happened” you are distancing yourself from your inner bliss. You are making your peace contingent on external events. There is a light that is always on inside of your heart. Some call this God or Tao or Buddha nature or Christ. If you stop chasing things looking for happiness out in the world, this light will grow brighter. If you become still enough, you can become this light and be reborn in the light.
